Our PVC van was sitting in the strong sunshine today on the driveway, with the sun shining hard on the side with the fridge vents.
It's fitted with a Thetford N3142 3-way fridge and this was switched off and no EHU to the van currently. Inside the van, the sun had warmed the interior up to around 27C by mid-morning and out of idle curiosity I went in and checked the freezer compartment expecting it to be as warm as the rest of the van. To my surprise it was really quite cool - not freezing - but definitely well below ambient temperature with the freezer walls cold to the touch.
I assume that convection currents in the refrigerant were causing the fridge/freezer to cool itself down somewhat. Just wondered if this was a recognised phenomenon as I haven't seen anyone mention it before.
